Geographical Information on Sandikhola

1 Background of Sandikhola Sandikhola is located in the Ghorka district of Nepal. This area is a mountainous area, isolated for steep terrain and steep terrain. 1 Location of Sandikhola The Ghorka district is located 140 kilometers west of the capital city of Kathmandu. It is in the mountainous area in the center. It is located at an altitude of 1259 meters above sea level. (2014 EWB Challenge) Figure 1: Map of the Golca region 2 Population of Sandikhola The population of Sandikhola is 456 people.

The Golca district of Nepal is located in the center of the territory in the south central part, near the center of Nepal. Specifically, the village of Sandikhola is located about 42 kilometers northeast of Bharatpur, it takes about 1 hour by car via unpaved roads and can only be accessed by 4 x 4 pass which can not be accessed in damp places. The village of Sandikhola is situated on the hillside of 1,256 m above sea level and is roughly divided into three sections: crops, houses and livestock.

The Sandikhola community has many problems related to water supply. This includes the availability of water resources, the cleanliness / quality of the water supply, the amount of water supplied, and the capacity of resources effectively used in domestic and production use. In Sandikhola, about 80% of WASH technology currently exists with small amounts of water, small waterways, 8 faucets and 2 spring entrances but in the dry season these entrances are inaccessible due to low pressure. When this happens, the community must pump water from the larger spring water in the village located further down the mountain. At the entrance of each spring, Sandikhola is a reservoir with three water quality testing machines throughout the village, a rain monitor and two flow monitors. By integrating the scope of these sources, systems and technologies, we have developed the MUS system

Geographic Information System (GIS) is an integrated spatial information system with functions to store, manage, analyze, display, and use geographic information. Meteorological data, in most cases, has spatial information such as the vertical distance (or atmospheric pressure level) from the ground, latitude, longitude and so on. It is best to use GIS technology to process weather data. Since 2008, the Hong Kong Observatory has used GIS technology to show the estimated rainfall distribution in the Pearl River Delta region including Hong Kong within the next two hours (Figure 1). With the geospatial information display software, users can configure the zoom in, zoom out, and panorama view operations to grasp the spatial extent of the rain zone.
